Introduction: Proximal Femoral fracture is one of the most devastating injuries in orthopaedic traumatology. In the past, these injuries were commonly noted in elderly person. With the industrial development, these injuries have become more common in young adults. This is mostly high velocity trauma and leads to unstable proximal femoral fracture. This has become a challenging fractures to treatment among the orthopaedic surgeons now a days Material and Method: My purpose to conduct a non randomized prospective study of the Role of Proximal Femoral nail in 50 adults with unstable Proximal Femoral Fractures. This study were be conducted in the Department of Orthopaedics PCMS, Bhopal. Result: One the basis of Haris Hip score functional assessment, at 1 year 33(66%) patients showed excellent results while 13(26%) patients showed good, 2(4%) patents fair, 2(4%) patients poor. Conclusion: Surgeon may treat the demanding unstable proximal femoral fracture with any type of fixation device as long as He/ She remembered that the fixation device will never make up for surgical failure. Therefore improvement in the treatment of unstable proximal femoral fracture were predominantly in the hands of the surgeon rather than in the hands of industries.
